Victoria Beckham isn’t the only Spice Girl to branch out into fashion. Melanie “Mel B” Brown debuted her Catty Couture Fall 2008 line at the California Market Center in downtown LA on April 7. While her fellow Spice Girls have not yet seen the designs, which feature high-waisted skirts, leggings, tank tops, and lots of leopard print, Brown tells PEOPLE, “We’re all really supportive of each other.” While some of the pieces lean toward the skimpier side, that’s nothing compared to her other venture: a Brazilian bikini line. “That’s been under wraps for many years because I just wear it,” she says of the designs, handmade by a woman in Brazil. As for this new feline-inspired line, the singer tells PEOPLE, “I’m so excited! It got pulled together quickly, really quickly. To actually see it, yeah, [it is] amazing.” And her favorite pieces from the line — her own outfit! “The high-waisted leather skirt and the jacket that I wore are my favorite pieces. It’s just that you can never go wrong with a leather, black high-waisted skirt. It goes with everything. It makes everything look clean and sexy.”
